My 250 (and I'm on eastern Long Island), has been to upstate NY, Pennsylvania, New Jersey, Delaware, Maryland, Connecticut, Rhode Island and Massachusetts. All over the place. Was about 10 miles from New Hampshire border as well. For now, 8 states.
I did about 300 miles round-trip into PA for a bike show. In the spring or summer, I may ride up to CT to visit my uncle who rides. I want to do more long rides. The Iron Butt Challenge has crossed my mind a few times.
